止するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combustion control device, and more specifically, when a combustion appliance having a liquid fuel vaporizer is operated at low temperatures, the vaporizer, which has been preheated by an electric heater, is supplied with low-temperature fuel. If the temperature of the vaporizer or combustion air comes into contact with it, the temperature of the vaporizer will drop rapidly, reducing the fuel vaporization ability and causing incomplete combustion. This prevents a decrease in vaporization ability.

。Conventional temperature controllers for fuel vaporizers include mechanical temperature controllers that utilize the temperature expansion of liquid or gas, and electronic temperature controllers that utilize the temperature characteristics of a thermistor. Since the adjustment range of the Ichikura is fixed, it was unavoidable that the vaporization capacity would decrease when the temperature of the feedstock or combustion air was low.

The electric heater 33 is heated by the current flowing through the electric heater 9, thereby heating the electric heater 33. When the temperature of the vaporizer 5 increases, the resistance value of the thermistor 9 installed near it decreases, and the inverting input voltage of the voltage comparator 22 gradually increases and exceeds the non-inverting input voltage, the output of the voltage comparator 22 decreases. As the voltage decreases, the pace voltage of the transistor 16, which is divided by the resistors 14 and 15, also decreases, and current flows to the relay 24 connected to the transistor 16, which is energized and the normally closed contact 29
is opened to cut off the current to the electric heater 33, and at the same time, the contact 17 is closed and the relay 26 is energized.
Contact 18 is also closed, forming a self-holding circuit.

完全燃焼を防止することができるのである。When the relay 26 is energized, the contact 3o is also closed and the blower motor 6 rotates, sending combustion air to the burner 1. At the same time, the sequence circuit 19 also operates, and the energization of the relay 26 closes the contact 31 and ignites. The device 7 is energized 2, and the relay 27 is energized to close the contact 32 and the fuel #I pump 3 starts operating. Then, fuel is pumped up from the fuel tank 4, and this fuel passes through the combustion device 6 and into the vaporizer 6.
The vaporized fried rice is ignited and combusted by the high-voltage electricity generated by the ignition device 7 discharging between the ignition electrode 8 and the burner 1. At that time, the vaporizer 5
Cooled by combustion air and fuel, the resistance value of the thermistor 9 increases and the inverting input voltage of the voltage comparator 22 decreases; Therefore, since the non-inverting input voltage of the voltage comparator 22 is slightly lower than the initial voltage, the voltage comparator 22 does not invert and the electric heater 33 is almost de-energized, but the combustion heat of the burner 1 is Some of it is recovered and the humidity in the vaporizer 5 gradually recovers, so stable fuel vaporization continues.However, if the temperature is low and the temperature of the combustion air and fuel is low, the humidity in the vaporizer 5 will gradually recover. As the temperature drops rapidly, the resistance of the thermistor 9 increases and the voltage comparator 22
° is finally reversed and the electric heater 33 is energized. However, in this case, incomplete combustion may occur due to a decrease in the vaporizing capacity until the temperature of the vaporizer 6 is recovered. Therefore, if the temperature detector 10 installed near the combustion air inlet is set to 9 so that its contact closes when the ambient temperature drops below the set value, the non-inverting input voltage of the voltage comparator 22 will be Resistor 12. Since a voltage is applied due to the parallel value of the resistor 13 and the division of the resistor 21, the voltage becomes higher than when the contacts of the temperature sensor 10 are open. Therefore, unless the resistance value of the thermistor 9 is further reduced, the voltage comparator 22 will not be inverted, and the temperature of the vaporizer 5 will become higher. That is, even if the contact point 17 is closed and the vaporizer 6 is cooled by combustion air and fuel, it is possible to maintain a temperature sufficient for vaporizing the fuel unless it is preheated to a high temperature in advance. Therefore, incomplete combustion can be prevented.
